MACHINE FOR PINNING PAPERS TOGETHER.

, Application filed July 31, 1922. Serial No. 578,663.

To all whom it may concern:

Be it knownthat I, HENRY F. BAUER, a citizen of the United States, residing at Wheaton, in the county of Traverse and State of Minnesota, have invented certain new and useful Improvements in Machines for Pinning Papers Togethenof which the following is a specification. This invention relates to devices for mechanically pinning together sheets of paper, such as documents and the like. An object of the invention, is to provide improved means, whereby headed pins may be quickly and securely applied to superposed sheets of flexible material in regular uniform order, and in selective positions thereon. to pin them together without in any way injuring the pin so that it may be available for fur-. ther use. i

It is very desirable in ollice practice, where it is required that papers be temporarily held togethcnthat the holding means used be absolutely dependabl iand yet be readily removable without appreciably distorting the papers. Paperclips, of which many types are at present in use, are objectionable in that the papers are easily separated, while other clips designed to be projected through the body of the papers and clinched or bent to prevent separation are not readily removable and also disfigure thepaper. It-is therefore common practice to use ordinary pins where security isdesired.

In my invention 1; use a pin angular eye for a head, and which is at present extensively used in place of ordinary pins, in that it has the advantage of lying fiat, as distinguished from the rolling of or:- dinary pins. The pin as here shown, has the further advantageof having a larger head so that it may not be so easily forced through the paper.

Other objects of the invention will be specifically pointed out as this specification progresses, the invention consisting in the construction, combination and arrangement of parts hereinafter to bedescribed and claimed. In the accompanying drawings :lorming part of this specification: 59 .Figure 1., is-a sideelevation of my improved paper pinning machine.

The invention comprises a base 1,.a housing 2, pivoted as by ,means; of the pivot/3 to the base to render itswingable in a vertical plane disposed longitudinally of said base; A compression spring 4t located forward'of said pivot and extending from said base to said housing, supports the latterin its normal inoperative upswung-positioinas shown in Figurel. Theb-ase is elongated and carries, preferably centrally, at one end the upstanding lug 5, which supports the pivot 3. Near its opposite end the base ,is formed with theupwardly extending. male die member oranvil 6,in longitudinal alinement with the housing. The housing is L shaped, and hasa. downwardly projecting base portion 8 which is. swingingly supported. upon the pivot, 3. The vertical leg of the housing is located above the anvil 6, and is normally slightly inclined to the right thereof and disposed preferably a t right angles to the horizontal leg. 9 of the L...,The 199 housing .is preferably formed of-two flat side plates joined together by tie members 10, 11 and 12, the lug 5 extending between the plates a suitable distance to. form ap-- preciably large side bearing surfaces whereby to maintain. the housing in vertical swingable position. The spring. 4, is held in place preferably between the vertical leg and base of the frame, by means of the stubs 13, extending respectively fromthe base and housing and telescoping respectively intotheends of the spring. Pivoted'by means of the pivot lit, on the housing, is the bell crank 15, the long arm thereof extending normally downwardly and inwardly to a point above and to the right of the anvil 6, (Fig. 1) and having pivotal connection 16 at said point with the forward end of the connecting link 17, said link having pivotal connection 18 at its rear end with'the cross head 19 which latter extends slidably between the plate members of the housing and slidably longitudinally of the housing, through the laterally alined slide ways 20 extending longitudinally of the horizontal An extensile spring 21 having connection with the cross head 19 and with the rear of the housing 2, yieldingly holds the cross head in the rear end of the slots 20. Secured to the cross head is the plunger 22, which latter slidably extends through the tie member 10 to slide longitudinally of the horizontal leg 9 of the housing. The forward portion of the plunger 22, is rectangular in cross section (Figs. 4c and 6) and slides in the guide block 23. fThe guide block is located at the juncture of the vertical and horizontal leg of the housing, between the anvil 6 and the pivot 3 and appreciably nearer the former than the latter. Further it is positioned in the housing so that it may bebrought into horizontal alinement with the jaw 7 of the anvil, when the housing is swung downward about its pivot. The guide block may be described as being formed with a central longitudinal .disposed slideway adapted to slidably receive the rectangular portion of theplunger which latter is formed by 22. The side walls 24 of the slideway are of less height than the thickness of the rectangular portion of the plunger. On either side o-f'said slideway and above the latter, the guide block is formed with. a rabbet, the walls 25, spaced outwardly respectively from the walls 24, the distance between the walls 25 being such as to loosely receive the triangular head 26 widthwise of the pin 26, when the pin is positioned longitudinally of the guide block as is clearly indicated by fine dotted .lines in Figure 2 of the drawings.

At its forward end the opposite walls 25 are overhung by an inwardly extending flange 27 to guide the pin head i'na sliding movement, the inner faces of said walls being adapted to receive slidably between them, the plunger 22. The guide block isfurther formed at its rear end with a transverse rib 28 which extends between the sides of the housing, said rib being perforated by a rectangular opening toslidably receive the plunger, which latter terminates preferably flush with the forward face 28 of said rib. Thus, when a pin of the type here shown, is

laidflatly in the groove or slideway of the guide block with its head immediately ad jacent the rib 28, and its side edgesres'ting respectively in the rabbets formed by the walls 25, a forward sliding movement of the plunger will engage the pin and project it forwardly through the guide block and through the'jaw 7 of the anvil, when the housing is manually held in down swung position as indicated in Figure '3 of the drawings.

, For the purpose of feeding pins from above downwards into a position to render them engageable by the plunger, as just described, I provide what may be termed a pin magazine, adapted to contain a removable rod or holder 29 upon which the pins are loosely strung to fall by gravity into the slideway of the guide block. The magazine is formed by the sidewalls of the vertical leg of the housing, between which the pins are adapted to descend, said side walls being provided with oppositely disposed downwardly extending long slender spring arms 30. These spring arms are bent toward each other from above downwards, to form a throat between them. which throat reduces gradually from the full width between the side plates of the housing, to a long narrow passage as at 31, through which the shanks of the pins project in their downward course. At their lower extremities the spring arms are bent inwardly to approximately contact, said lower extremity being located forward of the slidway in the guide block, in alinement with the end of the plunger 22, as is'clearly shown in Figures 1 and 3. At its top the housing is formed with a pair of oppositely disposed upwardly opening slots 32, and shoulders 33. Fitting between the side plates ofthe housing and adapted to slide with the shoulders 34: against the outer vertical edge thereof, is the rod head 35, said head having thumb screw 36 extending transversely through the body thereof. The thumb screw is adapted toslide in the slots 32 and the opposite sides of the side plates of the housing, are engaged, between the head 37 of the screw and the nut 37 threaded thereon whereby the head member may be slid into position to rest on the shoulders 33, as indicated in Figure 1, and be firmly secured in'place by means of the thumb screw 37. Supported in the head member 35, is the vertically disposed guide rod 38,

preferably triangular in cross section to fit loosely the triangular openings in the heads of the pins 26. This'guide rod extends to a point to just clear the top of the plunger 22, when the latter is actuated, as shown in Figure 6. Slidable on the rod is the gravity weight 39, which is adapted to rest'upon the pins strung on the rod, as shown in Figure l of the drawings, whereby the column of pins are urged downwardly into the guide pins will descend to place another in pro jectible position. The gap 40 between the rod 38 and the face 28 of the rib 28, is of a width to loosely permit the head of the pin to pass therethrough. For the purpose of controlling the column of pins to hold them in a plane I provide the-guide slot 41, which latter is formed preferably integral with the side plates of the housing. Thus, as the column of pins descend between the spring arms 30, the shanks thereof are guided in the guideway 41 adjacent the heads thereof, and are guided at their forward extremities by the spring arms 30, to be thereby held central of the 'slideway of l the guide block and the plunger.

For the'purpose of collectively crimping the sheets to be pinned together, the anvil 6 is provided, which latter extends approximately to the top side of the plunger when the mechanism is in operative posi tion (Figure 3). C o-acting with the anvil to crimp the papers, are the downwardly and rearwardly curved arms 42,. one on either side of the plunger and so positioned on the housing, that when the latter is swung into operative position, sufficient clearance between the anvil and said arms will be available to accommodate the maximum thickness of the; flexible material to be pinned. Forward of the anvil and also co-acting with the latter, isthe tension plate 43, having hinged mounting 4-4 in the housing to swing in the plane thereof, and being formed with a central opening 45 to clear the pins as they are projected. The tension plate is pressed into normal position by means of the coil spring 46, so that when paper packs of sheets of various thicknesses are placed upon the anvil the tension plate will yield under tension of its spring, and thereby press the paper against the anvil to hold it positioned during pinning operation.

Returning to the mechanism for actuating the plunger, the short arm of the bell crank 15 which is here shown extending at right angles to the long arm thereof, carries at its extremity the rotatably mounted roller 47 which latter rotates in a vertical longitudinal plane relative to the machine. The housing is furtherprovided with op posite vertical slots 48, wherein slides the actuating handle 49, the latter being formed with vertical ribs 50, which are adapted to en a e the housin frame whereb the actuating handle is rendered slidable vertically. A stop pin 51' restricts the vertical movement of said handle. The handle is further formed with a cam arm 52, the lower edge thereof being in engagement with the roller 47, whereby, when said handle is depressed the bell crank will be rotated aboutits pivot 14, and thereby ac tuate the plunger 22.

For the purpose of delaying actuation of the plunger for a predetermined period of time, to permit the housing to be bodily swung about its pivot 3 to effect a paper crimping operationthe tripping. lever 53 is provided. This lever has fulcrum support 54 on thehousing, to swing in a plane parallel with the latter, and is formed with an outstanding arm 55 adapted to engage the notch 56 in the lower edge of the conmeeting link 17. Thus, as indicated in dotted lines in Figure 1, the housing may be bodily} rotated about the pivot until the lever 53. engages with the top of the anvil 6, without operating the plunger, owing to the interlocking engagement of the arm 55 with the notch 56. A further depression action of the handle 49, will cause the lever 53 to be rotated about, its pivot 54 and therebycause it to disengage the notch 56 and cause the lock 17 to be pulled forward and thus actuate the plunger. When the plunger is in its fully projected posi tion, the lever will have assumed the position indicated in Figure 3. Thevertical leg of the housing is here shown approximately at right. angles to the base and is shown resting with its underside 57 upon the papers which are indicated in dotted lines. in crimped position on the anvil. Here the pin is shown ashaving been projected through the papers and the tension member 43 shown in yielding position. In order to afford cushion effect for the head of the pin I provide thespring plate 58 positioned on thefront sideof the guide block 23 below the slideway therein, and extend ing a trifle above the floor thereof, whereby when the pin is driven home the head thereof will be afforded a resilient support thereby. As a martial actuationof the. machine would result in an imcomplete pin projecting movement, and thereby beapt to disturb regularity of feed in the pin mag-as zine, I have provided'means wherebyany partial actuation of the device must be com. pleted before the machine. can. resume its normal state for further actuation, This mechanism comprises a straight rack. having upwardly and forwardly directedv teeth 59, and an overhanging side plate 60 spaced upwardly therefrom and disposed parallel therewith, said rack and plate being preferably mounted. on the side of the base portion of the housing. 1

Ext-ending from a point midway of the pivot 64 near the lug 63, is the weighted lever 65, formed with; a nose 66 extend ing above said pivot and having an oblique forwardlyfacing face-relative to the body of the lever.

the oblique face of thelever 65 to assume the position indicated in dotted lines ure 1), the nose 66 thereof riding on the underside of the plate 60.

' As the stroke of the plunger advances the weighted lever, holds (by gravity) the plate 66 in engagement with the teeth until the end of the stroke is reached, at whichtime the nose 66 of the lever is freed from the plate 60, thereby permitting the lever 65 to assume a plumb position, as shown in Figure 3, in which position the nose extends beyond the top of the plate 60. Obviously, a return movement of the plunger will cause the plate 66 to ride over the top of the plate 60, thereby lifting the rear end of the pawl lever 62 out of engagement with the teeth 59, as indicated in dotted lines in Figure 1. As the lever 65 reaches the end of the plate 60 it will fall by gravity upon the rack and permit the plate 63 to reengage the teeth. Thus, an incomplete paper pinning operation cannot be corrected by a reverse movement of the parts, whereby disarrangement and clogging of the pins is avoided. V

In Figure 9, two sheets of paper are shown pinned together by my improved pinning device, pins here shown being disposed at right angles to the top edge of the sheets. For the purpose of guiding the sheets so that the pins may be inserted in a row parallel with the top thereof, the gauge plate 68 is provided, the latter being secured by-means of the set screw 69, tothe base 1, said gauge plate having a central elongated slot 70, whereby it may he slid back and forth or laterally, so that the operator may selec. tively position the pins onthe sheets; The anvil and the members 42 and 43 co -act to constitute die instrum'entalities for crimping the, sheets, while the gauge plate 68 serves as a means for controlling the point of applic ation of the pins.
